Is There a Producer Price Index for Industrial Gas Manufacturing?

PCU325120325120 is the Bureau of Labor Statistics' Producer Price Index industry series for Industrial gas manufacturing, NAICS 325120. The identifier itself is the definition: PCU marks a PPI industry series, 325120 is the NAICS industry code, and the trailing 325120 repeats as the product code, so the series prices the output of the industry as a whole rather than any single gas. It is published not seasonally adjusted and quoted against a fixed Base Date of December 2003 = 100 (shown as 200312 in the catalog block).

Each observation carries four fields: seriesID (PCU325120325120), year, period (M01-M12 for months, M13 where an annual average appears) and value. Datadory records roughly 500 monthly observations for the single series at quality score 8 - and it is one of only two producer-price-index records among the 1,744 datasets Datadory catalogs, the other covering telephone apparatus manufacturing. For industrial gases that makes it the direct producer-price benchmark: nothing else in the pool prices this industry's own output.

The series reaches back to at least 1985 and runs through the current month, which is why roughly 500 monthly observations sit in the catalog. Coverage notes flag one caveat worth knowing before you cite an exact start date: the captured rendering begins in the mid-1980s, so the true first observation is best confirmed against the complete history rather than assumed from a preview.

Recency has its own rule. Preliminary months carry a (P) flag, and BLS states that all indexes are subject to revision up to four months after original publication. In the observed sample, July 2026 printed 297.217(P) while April-June 2026 were also flagged preliminary - so any analysis built on the trailing quarter should re-pull the series before it is quoted.

The fastest fit-check is looking at rows. Request a sample of the series and recent months arrive side by side with their preliminary flags - the same (P) markings described above - so revision behaviour can be inspected rather than taken on faith.

Yes, and three documented properties shape the drafting. First, reference the full series ID PCU325120325120 explicitly rather than 'the BLS gas index', because the ID fixes both the industry (NAICS 325120) and the product scope. Second, state whether resets use monthly values or annual averages - annual averages are derived from the same monthly series rather than issued as a separate release, so both parties can reproduce them identically. Third, require a re-read of the trailing four months before invoicing, because preliminary (P) prints revise within that window.

The base convention matters just as much when drafting: every value quotes against December 2003 = 100, so escalation clauses should specify percentage change rather than raw levels if they want the formula to survive a future rebasing.

The index prices an industry without naming a single firm. Three related-pool records supply the company layer:

• Compressed Gas Association - Company Member Directory - a flat HTML roster of roughly 157 CGA member companies (manufacturers, distributors, suppliers and transporters of gases and cryogenic liquids) plus about 28 partner and affiliated associations.
• Airgas Store & Branch Locator - public pages covering roughly 900 US retail locations with address, phone, hours, coordinates and service lines, useful for mapping the distribution footprint that carries priced gas to buyers.
• Cognite Open Industrial Data - Valhall Gas Treatment Plant - a reference feed exposing the first-stage gas treatment and compression system of the Valhall PH platform as time series, assets, events, files and 3D models.

A contract analyst can therefore read the price (PCU325120325120), name counterparties (CGA roster), check local delivery coverage (Airgas) and inspect real plant telemetry (Valhall) without leaving the pool.

For the full pool behind this page - all 17 industrial gases records, from EIGA's statistics booklet to EPA's facility data - read the industrial gases data guide, which lays out coverage, fields and use cases side by side. To go deeper on the series itself, open the BLS Producer Price Index - Industrial Gas Manufacturing (PCU325120325120) record with its field list and observed values, and pair it with Industrial Production & Capacity Utilization (G.17) so the price line always has a volume line beside it.
